idpf: cancel mailbox work in error path

Browse Source 
In idpf_vc_core_init, the mailbox work is queued
on a mailbox workqueue but it is not cancelled on error.
This results in a call trace when idpf_mbx_task tries
to access the freed mailbox queue pointer. Fix it by
cancelling the mailbox work in the error path.

Fixes: 4930fbf419 ("idpf: add core init and interrupt request")
